There are plenty of different ways in which you can accomplish this. You could create a module with a non-breaking space character as the only content:You could also create a module with a specific module class suffix parameter, then use CSS to hide the content of that module. For example, if I create a CustomHTML module with a module class suffix of "hidden-content", I could add the following to my CSS to hide the content of that particular module:.hidden-content .rt-module-surround {display:none;}
